Very cool, is it possible to add voting for multiple dates too?

Right now nope, but I'm planning to add new features.

This is cool looking but you should note in the front page that it has ical, et al. calendar features.

How does it compare to Mobilizon?

It's similar, but not that good as Mobilizon, Im focusing on simplicity with an improved UI and experience.

I'm assuming easier to spin up a new instance on your own, but this is my personal opinion.

Smoke Signal has a similar system on ATProto (no affiliation)

I believe this is the project that has the Rust code (on the GitHub of ATProto)

API, Please make an API? I could integrate my RSVP system into it which requires more specific features but could use this to create the base for the event.

Do you have plans for adding ActivityPub support in the future? That would be very cool, and having interop with these other FOSS projects will help give things network effects.
